Fuss about daughter, much loved (6)
I believe the answer is:
adored
'much loved' is the definition.
(I've seen this in another clue)
'fuss about daughter' is the wordplay.
'fuss' becomes 'ado' (synonyms).
'about' becomes 're' (regarding).
'daughter' becomes 'd' (genealogical abbreviation).
'ado'+'re'+'d'='ADORED'
(Other definitions for adored that I've seen before include "Loved intensely" , "Worshipped and revered" , "Worshipped, loved" , "Loved, venerated" , "Loved dearly" .)
